GPT-4.1
OpenAI's flagship API model for 2025, excelling at advanced programming, large datasets, and complex instructions. Outstanding for code-heavy and technical projects, with a massive context window and top-tier coding/instruction-following performance.
GPT-4.1 Mini
Balanced speed, cost, and intelligence. Matches or exceeds GPT-4o in many benchmarks, with much lower latency and cost. Ideal for high-frequency, cost-sensitive, or latency-critical applications.
GPT-4.1 Nano
Fastest and most affordable in the 4.1 family, designed for simple, high-frequency, or edge tasks, while retaining the large context window.
o1
OpenAI's previous top reasoning model, now superseded by o3. Still strong at structured reasoning, science, planning, and math.
o3 Mini
Fast, cost-efficient reasoning model, strong at math/coding/vision, with a large context window and integrated multi-tool use.
Claude 4 Sonnet
Anthropic's hybrid reasoning model with superior intelligence for high-volume use cases and advanced coding capabilities.
Gemini 2.5 Pro
A powerful reasoning model from Google for complex problem-solving and multimodal tasks.
Gemini 2.5 Flash
Google's first hybrid reasoning model, balancing performance with speed and cost-efficiency.
